Annotated Sequence Record

Tomato (Solanum lycopersicum) is a crop of growing importance throughout West and Central Africa. Recently, several begomoviruses (genus Begomovirus; family Geminiviridae) have been associated with leaf curl and yellow leaf curl symptoms in tomato crops in West Africa, including tomato yellow leaf curl Mali virus (TYLCMLV), tomato yellow crumple virus (TYLCrV), tomato leaf curl Mali virus (ToLCMLV), tomato leaf curl Nigeria virus (ToLCNGV), tomato leaf curl Ghana virus (ToLCGHV), tomato leaf curl Kumasi virus (ToLCKuV) and tomato leaf curl Togo virus (ToLCTGV) [3, 7, 10, 15]. These viruses are transmitted by the whitefly Bemisia tabaci (Genn.) sibling species group, and they have a genome of single-stranded (ss) DNA (about 2.7-2.8 kb) with an organization typical for Old World monopartite begomoviruses [11]. In addition, many monopartite begomoviruses are associated with alphasatellite and betasatellite molecules that may influence symptom development, pathogenicity, and virulence [1, 3...
